Developing urban and peri-urban ecosystem services with nature-based solutions (NBS) and participatory approaches can help achieve more resilient and sustainable environments for cities and urban areas in the face of climate change. The co-creation process is increasingly recognised as the way forward to deal with environmental issues in cities, allowing the development of associated methods and tools that have been described and published for specific stages. It is argued that the co-creation process comprises various interlinked stages, corresponding stakeholders, and subsequent methods and tools that need to be mapped and integrated across all stages. In this study, a Life Cycle Co-Creation Process (LCCCP) for NBS is developed, building on continuous improvement cycles and Design Thinking methodologies, and for which the stages and substages, involved stakeholders and engagement methods and tools are mapped and defined. For stakeholders, the actors of an Urban Living Lab (ULL) are adapted to the LCCCP; for the engagement methods and tools, the goals of stakeholder engagement are used as a guide to select examples of co-creation methods and tools. The developed LCCCP comprises five stages, i.e., CoExplore, CoDesign, CoExperiment, CoImplement and CoManagement, creating a unique path that can be followed by practitioners for NBS co-creation.

O aumento da frequência, intensidade e recorrência dos fogos rurais nos países do Sul da Europa, e em particular em Portugal, tem evidenciado a necessidade de definir uma estrutura de gestão florestal pós-fogo, que atue no risco de degradação dos ecossistemas a nível local, na prevenção de potenciais danos nos valores em risco a jusante, na promoção da regeneração florestal e na diminuição da frequência e severidade de incêndios futuros. Este artigo pretende discutir a(s) abordagen(s) à gestão florestal pós-fogo, através de uma revisão da literatura científica usando como termos de pesquisa ‘post-fire management’ e ‘forest’, e da análise dos discursos de agentes responsáveis pela operacionalização de projetos de gestão pós-fogo, financiados no âmbito do Programa de Desenvolvimento Rural em Portugal. Os resultados revelaram que a gestão florestal pós-fogo é um tema recente, de natureza complexa e dinâmica, que tem estado mais focado na componente ecológica. No entanto, existe um reconhecimento progressivo da importância de integrar novos aspetos, tais como a análise de custo-benefício e o envolvimento dos agentes.

The most critical question for sustainability research is how to facilitate transformative change. Yet, the academic scope of historical commons’ research is limited to institutional design and environmental sustainability. In this paper we argue for a transformative research agenda for historical commons focused on the study of processes building humans and more-than-human communities. We start by reviewing three commons schools, namely the mainstream and critical institutionalism and the community economies collective, and assess how these relate to sustainability and to theories on agency, community and change. We then define a research agenda taking a political and critical ontology of the community economies collective, and a phenomenological epistemology of critical institutionalism. We follow by characterising the underlying practices building humans and more-than human communities by showing three ideal stages of commoning found in our empirical cases in the north-western Iberian Peninsula (Spain and Portugal). Finally, we end by presenting a guiding framework for analysing processes of building communities in historical commons. In conclusion, we encourage further exploration of underlying practices that widen humans’ interdependency and inter-being and call for action-research projects and experimental methods that promote transformative encounters between humans and nature. Our framework is a first attempt to inspire researchers of historical commons to actively engage in unravelling the full potential of historical commons as sites of transformation.

In recent decades, European rural development policies have transitioned toward a more place-based approach. This claim rests on the assumption that the diversity of resources within rural areas can be a potential source for place-shaping practices and sustainability. Moreover, this shift away from a top-down sectorial toward a more territorial focus has also shed light on the importance of agency, relations, and how people engage. Many rural areas in Europe, and particularly in Portugal, have seen a withdrawal of focus away from agriculture toward more diversified activities, where place-based approaches can untap local potential, stimulate sustainable place-shaping practices, and create significant well-being. However, some rural communities have difficulties in capitalizing on them due to unfavorable demographics such as depopulation and aging, a focus on traditional industries, and a lack of technical knowledge. The aim of the article is to discuss the role of place-based policies for enabling place-shaping practices revolving around traditional resources in rural areas and their contribution to sustainability. The study briefly highlights the recent debate around European rural development policies and illustrates their implementation through place-shaping practices via a case study in a Portuguese rural village—Várzea de Calde. The village revalorized itself and is trying to tackle marginalization processes through its traditional linen, which is a local material and immaterial resource, via collective agency and a strong sense of identity. The case study will provide empirical insights in discussing the effects of sustainable place-shaping practices stimulating by place-based policy instruments. Our conclusions highlight the positive contributions toward sustainability through improvements in social (e.g., identity) and economic well-being.

Only a few studies have quantified and measured ecosystem services (ES) specifically related to soil. To address this gap, we have developed and applied a methodology to assess changes in ecosystem services, based on measured or estimated soil property changes that were stimulated by soil management measures (e.g., mulching, terracing, no-till). We applied the ES assessment methodology in 16 case study sites across Europe representing a high diversity of soil threats and land use systems. Various prevention and remediation measures were trialled, and the changes in manageable soil and other natural capital properties were measured and quantified. An Excel tool facilitated data collection, calculation of changes in ecosystem services, and visualization of measured short-term changes and estimated long-term changes at plot level and for the wider area. With this methodology, we were able to successfully collect and compare data on the impact of land management on 15 different ecosystem services from 26 different measures. Overall, the results are positive in terms of the impacts of the trialled measures on ecosystem services, with 18 out of 26 measures having no decrease in any service at the plot level. Although methodological challenges remain, the ES assessment was shown to be a comprehensive evaluation of the impacts of the trialled measures, and also served as an input to a stakeholder valuation of ecosystem services at local and sub-national levels.

Wildfires are well-known to increase runoff and erosion during the initial stages of the window-of-disturbance, and mulching has been widely documented to effectively minimize this impact. However, the relationship between the rate of mulch application and erosion reduction is poorly studied, in spite of its potential importance for optimizing mulching costs and efforts per ha. Therefore, a field experiment was carried out in a recently burnt eucalypt plantation in Central Portugal that had been burnt by a moderate severity fire during August 2015, comparing sediment as well as organic matter losses from three untreated 2 m × 8 m erosion plots with losses from six plots mulched with eucalypt logging residues at two contrasting rates of either 2.6 or 8.0 Mg ha–1. The two mulching treatments resulted in the targeted litter covers of 50 and 79%, and these covers hardly changed over the ensuing year. Over this first post-fire year, the mulched plots produced significantly less mineral soil as well as organic matter losses than the untreated plots. At the same time, the plots with the high mulching rate lost consistently less sediments and organic matter than the plots with the low mulching rate but the differences were not statistically significant over all measurement periods. Total sediment losses over the first post-fire year were, on average, 86 and 96% lower following mulching at 2.6 and 8.0 Mg ha–1, respectively, than without mulching. In absolute values, total losses dropped from 8.0 to 1.1 and 0.3 Mg ha–1 y–1, respectively, or, in other words, similar to and well-below the widely-accepted threshold of tolerable soil loss of 1 Mg ha–1 y–1. If this threshold value is acceptable to land managers, they could treat a three times larger area with the same amount of mulch.

With the increasing pressure to improve the contribution of forests to help dealing with global changes, it is critical to understand the different perceptions of those involved in the forest. How do forest owners, managers andmembers of local communitieswho often depend on the forest, value it and what are the problems affecting the forests in terms of being able to meet these new challenges? In Portugal, this task has taken on an even greater priority as more than 90% of the forest is private and forest management relies on the individual decisions of thousands of forest owners. To understand stakeholder views on forest and forest management, a transversal social perception survey was implemented in the form of a case study of central Portugal which included decision-makers, local technicians, forest owners and the general public. The results show that there is a consensus on the main issues affecting forests and forest management. A shift from classic forest owners to the emergence of indifferent forest owners was observed, although this shift has not been recognized by the forest owners in the survey, who maintain the individual management of their properties

Forest fires affect Portugal and other southern European countries to a greater or lesser extent every year, causing severe environmental, social, and economic damage. This research is based upon the analysis of the results of a case study on the technical and social perceptions of multiple dimensions of forest fires in Portugal, which brings together the views and perspectives of different entities with expertise in forest management and in forest protection against fires, forest owners, and members of the public. Assessing perceptions of forest fires has proved to be relevant when it comes to a greater involvement of the local population in forest management. The results show that the opinions of local respondents were consensual in identifying crime as the main cause of the forest fires. Additionally, it is the repeated failure to clean the forest biomass which cause the rapid spread of forest fires. Damage caused to the environment was more of an issue with the local forestry technicians, and economic issues were at the forefront for the local community. Various solutions were put forward to mitigate these problems, but everyone agreed that cleaning the forests biomass and punishing arsonists should be at the top of the list of priorities.

Fires are the main driver of land degradation in forest areas in Mediterranean sub‐humid regions and are likely to increase as a result of climate and other global changes. To prevent deleterious processes induced by fire, several policies and strategies have been implemented at national and regional scales. We perform a comparative study of policies and strategies of Portuguese and Spanish (Comunitat Valenciana) cases in order to assess the differences between them and identify their roles in forest fire prevention and in combating and mitigating impacts. To this end, we analyse the sustainability objectives stated in the legislation of each country to identify the strategies used to deal with forest fires and the extent to which they are integrated to achieve the sustainability objectives they pursue. The comparative analysis includes an assessment of sustainability, evaluated by the explicitness of the objectives, and identification of how the lines of action contribute to reach these objectives. We found different levels of complexity and that the adoption or rejection of some of the techniques is closely related to the tradition and the experience of local communities. This analysis highlights the importance of local characteristics and the stakeholders, involvement in designing effective strategies to reduce fire risk. Copyright © 2014 John Wiley & Sons, Ltd.

Indicator-based approaches are often used to monitor land degradation and desertification from the global to the very local scale. However, there is still little agreement on which indicators may best reflect both status and trends of these phenomena. In this study, various processes of land degradation and desertification have been analyzed in 17 study sites around the world using a wide set of biophysical and socioeconomic indicators. The database described earlier in this issue by Kosmas and others (Environ Manage, 2013) for defining desertification risk was further analyzed to define the most important indicators related to the following degradation processes: water erosion in various land uses, tillage erosion, soil salinization, water stress, forest fires, and overgrazing. A correlation analysis was applied to the selected indicators in order to identify the most important variables contributing to each land degradation process. The analysis indicates that the most important indicators are: (i) rain seasonality affecting water erosion, water stress, and forest fires, (ii) slope gradient affecting water erosion, tillage erosion and water stress, and (iii) water scarcity soil salinization, water stress, and forest fires. Implementation of existing regulations or policies concerned with resources development and environmental sustainability was identified as the most important indicator of land protection.

An approach to derive relationships for defining land degradation and desertification risk and developing appropriate tools for assessing the effectiveness of the various land management practices using indicators is presented in the present paper. In order to investigate which indicators are most effective in assessing the level of desertification risk, a total of 70 candidate indicators was selected providing information for the biophysical environment, socio-economic conditions, and land management characteristics. The indicators were defined in 1,672 field sites located in 17 study areas in the Mediterranean region, Eastern Europe, Latin America, Africa, and Asia. Based on an existing geo-referenced database, classes were designated for each indicator and a sensitivity score to desertification was assigned to each class based on existing research. The obtained data were analyzed for the various processes of land degradation at farm level. The derived methodology was assessed using independent indicators, such as the measured soil erosion rate, and the organic matter content of the soil. Based on regression analyses, the collected indicator set can be reduced to a number of effective indicators ranging from 8 to 17 in the various processes of land degradation. Among the most important indicators identified as affecting land degradation and desertification risk were rain seasonality, slope gradient, plant cover, rate of land abandonment, land-use intensity, and the level of policy implementation.

There are many, often competing, options for Sustainable Land Management (SLM). Each must be assessed - and sometimes negotiated - prior to implementation. Participatory, multi-stakeholder approaches to identification and selection of SLM options are increasingly popular, often motivated by social learning and empowerment goals. Yet there are few practical tools for facilitating processes in which land managers may share, select, and decide on the most appropriate SLM options. The research presented here aims to close the gap between the theory and the practice of stakeholder participation/learning in SLM decision-making processes. The paper describes a three-part participatory methodology for selecting SLM options that was tested in 14 desertification-prone study sites within the EU-DESIRE project. Cross-site analysis and in-depth evaluation of the Moroccan and Portuguese sites were used to evaluate how well the proposed process facilitated stakeholder learning and selection of appropriate SLM options for local implementation. The structured nature of the process - starting with SLM goal setting - was found to facilitate mutual understanding and collaboration between stakeholders. The deliberation process led to a high degree of consensus over the outcome and, though not an initial aim, it fostered social learning in many cases. This solution-oriented methodology is applicable in a wide range of contexts and may be implemented with limited time and resources.

To the South of the Douro and within the Vouga river systems, not far from the Atlantic coast, the Northwest Beira Highlands rise steeply from the coastlands and plains. They are composed of small mountains, but have a very marked relief because the Hercynian Massif (Maciço Antigo), after suffering repeated folding, granitization and metamorphism, has been greatly worn down by erosion (Ferreira, 1978). They include the Montemuro Mountain in the South Douro river system, the Gralheira Massif (Freita, Arada and Arestal hills), and the Caramulo Mountain to the South (see location map of Portuguese continental highlands in the introductory article to this chapter).

The paper reflects on how populations prone to flood risk perceive such hazards and the way this perception has or has not been incorporated into the measures and mechanisms of flood risk management. The frequent occurrence of flooding, as well as the population's vulnerability and exposure to this risk, shows that the municipality of Águeda is a paradigmatic case for analysis of these issues. Similar to the rest of the country, the municipality of Águeda has been neglecting the multidimensional nature of flood risk. The data collected present some disparity between the proposals and technical perspectives regarding the management and mitigation of flood risk and the perception of local populations. In addition, neither knowledge of social perception of flood risk nor of the local communities is being integrated in a substantial and pro‐active way, whether in the processes of policy‐making or in the implementation of these policies. Empirical evidence equally shows that there is a clear tendency towards acceptance and coping with flood risk by the population in the municipality of Águeda. This seems to be connected to the local populations' recognition that though it is impossible to eliminate risk, there are at the same time advantages to occupying the floodplains.

Objetive: To evaluate the effects of conjugated equine estrogens (CEE) on the pilocarpine-induced epilepsy in rats. Study design: 40 female rats were divided into: GPC (positive control) presented ""status epilepticus"" (SE) induced by pilocarpine; GOC(ovariectomized control) only castrated; GNC (negative control) received only saline solution; GPE received pilocarpine, presented SE, castrated and received 50 mu g/kg CEE treatment; GPV received pilocarpine, castrated and received propylene glycol (vehicle). The animals were monitored by a video system. At the end of observation, the brains removed for later histologic analysis using Neo-Timm and Nissl methods. Results: The GPE presented a reduction in number of seizures compared to GPV. The Neo-Timm analysis showed that GPV had greater sprouting of mossy fibers, with a denser band in the area of the dentate gyrus hilum compared to GPE. On Nissl staining, GPE showed evident neuronal loss in the CA3 area. GPV presented loss in CA1 and dentate gyrus. Conclusion: Estrogen may have a protecting effect on the central nervous system.

The aim of the present work was to analyze the effects of pinealectomy in the development of the epilepsy model induced by pilocarpine in adult male rats. Group I: Wistar male adult rats were submitted to pinealectomy, and 7 days after surgery, these animals received pilocarpine (350 mg/kg, i.p.) to induce three distinct behavioral phases: status epilepticus, seizure-free, and chronic phases. This late, as well as all control groups were continuously video-recorded for 60 days, to study behavior parameters. These animals were killed and the brain sections were processed for Nissl and neo-Timm. Group II: Another group, also submitted to pinealectomy, received several injections of melatonin (2.5 mg/kg): 20 min before, concomitantly with pilocarpine, 30 min, 1 h, and 2 h after pilocarpine administration. Some animals from group I and all from group II were sacrificed 48 h following status epilepticus onset to perform TUNEL assay. The latency for status epilepticus onset, status epilepticus length as well as mortality rate during status epilepticus were similar for pinealectomized and control groups. On the other hand, pinealectomized rats presented minor duration of the silent period, a higher number of spontaneous seizures during the chronic phase, increased number of TUNEL-positive cells (acute phase), increased neuronal loss, and marked supragranullar mossy fibers sprouting (chronic phase) in the hippocampal formation, when compared with control groups. Our data show that the pinealectomy facilitates the epileptogenic process that follows the long-lasting status epilepticus. This facilitation can be partially reverted by the simultaneous administration of melatonin.
